Answer: Methodologies are comprehensive, multiple-step approaches to systems development Techniques are particular processes that you follow to help ensure that your work is complete, well-done, and understood by others Tools are typically computer programs that make it easier to use and benefit from techniques and to follow faithfully the guidelines of the overall development methodology The techniques and tools should support the chosen methodology Methodologies, techniques, and tools work together to form an organizational approach to systems analysis and design L.O.: 1.1 Describe information systems analysis and design CLLO: Describe the components of an information system (IS) Classification: Synthesis AACSB: Information Technology, Application of Knowledge 95) Briefly define the term system Answer: A system is an interrelated set of procedures which are used within one business unit to work together for some purpose Systems have a distinct purpose, such as keeping track of customer orders or paying vendors for supplies L.O.: 1.1 Describe information systems analysis and design CLLO: Describe the components of an information system (IS) Classification: Synthesis AACSB: Information Technology, Application of Knowledge 96) Describe the term component as related to systems Discuss how components can work together Answer: A system is made up of components, which are either irreducible or an aggregate of other components Within a system, components are interrelated in such ways that one component might work with another component in order to accomplish one of the tasks which the system is designed to complete L.O.: 1.1 Describe information systems analysis and design CLLO: Describe the components of an information system (IS) Classification: Application AACSB: Information Technology, Application of Knowledge 97) Describe what decomposition is used for Answer: Decomposition results in smaller pieces of a system which are then easier to work with This is accomplished by breaking a system down into smaller components Decomposition allows the systems analyst to focus attention on one area of the system, focus on one part of the system pertinent to a group of users and build parts of the system independently L.O.: 1.1 Describe information systems analysis and design CLLO: Describe the components of an information system (IS) Classification: Application AACSB: Information Technology, Application of Knowledge 29 Copyright © 2015 Pearson Education, Inc 98) Why is coupling not advantageous for systems? Answer: Coupling occurs when subsystems are dependent upon each other In general, subsystems should be built to be independent of each other In this way, if one subsystem fails then the other is not impacted L.O.: 1.1 Describe information systems analysis and design CLLO: Describe the components of an information system (IS) Classification: Synthesis AACSB: Information Technology, Application of Knowledge, Analytical Thinking 99) Describe the role of a systems analyst Answer: A systems analyst has the primary role to study the problems and needs of an organization to determine how to best combine people, methods and information technology in order to improve the organization In addition, he or she helps users and business managers define their requirements for a project L.O.: 1.2 Describe the role of the systems analyst in information systems development CLLO: Describe the components of an information system (IS) Classification: Application AACSB: Information Technology, Application of Knowledge 100) Discuss the types of skills needed in order to succeed as a systems analyst Answer: Systems analysts need to develop four types of skills in order to succeed Analytical skills are needed to understand the organization and its functions, identify opportunities and problems and to analyze and solve problems Technical skills help you to understand the potential and limitation of information technology Management skills help you to manage projects as well as the people involved Finally, interpersonal skills help you to work with users as well as other members of the technical team L.O.: 1.2 Describe the role of the systems analyst in information systems development CLLO: Describe the components of an information system (IS) Classification: Application AACSB: Information Technology, Application of Knowledge 101) List and briefly describe the four major SDLC phases Answer: The four phases are systems planning and selection, systems analysis, systems design, and systems implementation and operation Systems planning and selection is the first phase of the SDLC, in which an organization's total information system needs are analyzed and arranged, and in which a potential information systems project is identified and an argument for continuing or not continuing with the project is presented During systems analysis, the current system is studied and alternative replacement systems are proposed During systems design, analysts convert the description of the proposed system into logical and then physical system specifications During systems implementation and operation, the information system is coded, tested, and installed in the organization During this phase the system is systematically repaired and improved L.O.: 1.3 Describe the information systems development life cycle (SDLC) CLLO: Describe the components of an information system (IS) Classification: Synthesis AACSB: Information Technology, Analytical Thinking 30 Copyright © 2015 Pearson Education, Inc 102) List and briefly discuss six approaches to systems development Answer: Prototyping, Computer-Aided Software Engineering tools, joint application design, rapid application development, Participatory Design, and Agile Methodologies are the six approaches mentioned in the textbook Prototyping is an iterative process of systems development by which requirements are converted to a working system The prototype is continually revised through close work between an analyst and users The analyst builds the prototype from requirements supplied by the end users Once the prototype is completed, it is evaluated by the end users Based on the feedback provided by the end users, the analyst will modify the prototype This results in an iterative process that continues until users are satisfied Computer-aided software engineering (CASE) tools provide automated support for some part of the systems development process Joint application design (JAD) is a structured process in which users, managers, and analysts work together for several days in a series of intensive meetings to specify or review system requirements By promoting group participation, time and organizational resources are better managed Also, the group is more likely to develop a shared understanding of the IS purpose Rapid application development (RAD) is a systems development methodology created to radically decrease the time needed to design and implement information systems Participatory Design is a systems development approach that originated in northern Europe, in which users and the improvement in their work lives are the central focus Agile Methodologies focus on adaptive methodologies, people instead of roles, and an overall self-adaptive development process L.O.: 1.4 List alternatives to the systems development life cycle, including a description of the role of computer-aided software engineering (CASE) tools in systems development CLLO: Describe the components of an information system (IS) Classification: Application AACSB: Information Technology, Application of Knowledge 103) Briefly discuss prototyping Answer: When one designs and builds a scaled-down version of a system, this is called prototyping A prototype can be built with a CASE tool, which automates many of the steps in the systems development life cycle The prototype is given to the user for feedback and then revised as needed This is done iteratively The key advantages to this approach are: involvement of the user in the design of the system and the ability to capture requirements in a concrete format L.O.: 1.4 List alternatives to the systems development life cycle, including a description of the role of computer-aided software engineering (CASE) tools in systems development CLLO:
